The building type changes the method
In a converted tobacco-warehouse loft with a concrete slab, a curbless shower often means saw-cutting for a new drain line. In a wood-framed bungalow, it's a framing and joist question instead. Either way, the slope to the drain is what actually keeps water where it belongs.
Build a complete scope
- Achieving fall to drain within the depth an old floor allows
- Glass or screen support fixed into framing rather than tile
- Continuous waterproofing from pan to wall, checked before finishing
- Extraction ducted outside, not into the attic
- Permits, inspections, protection of the route out, and the warranty
Durham context
Durham combines nineteenth-century tobacco and textile districts, early streetcar neighborhoods, postwar ranches, and fast-growing suburban edges. Knowing whether a house sits on concrete, crawlspace, or slab changes the approach before finishes ever get discussed.
